I first tested out the display itself, and found the TFT_eSPI to work well. For reading the touchscreen, I only really tested position and haven't looked into gestures yet, but I found that both RAK14014-FT6336U and the Arduino-FT6336U libraries worked equally well for what I tested. The RAK library actually used up a bit more program memory, about 240 bytes more, so if your processor is small in that department, might consider that. Here are some tidbits that I needed to learn through experimentation that might help others get running quicker: 1) SPI interface to the display runs well at 80MHz. I used ESP32 DEV, so no problem. 2) On ESP32, use default SPI pins in order to use hardware driver, which is fastest. 3) On I2C interface for touchpad, use default pins for SDA and SCLK. Easiest way to check which pins these are is to print out SDA and SCLK to the serial port. 4) The FT6336U interrupt pin is mostly useful to wake up the processor while in a sleep state. During normal operation, interrupts constantly come in and cannot easily be used to determine when a touch has happened. Need to poll the TD_STATUS register to see if non-zero and not use the interrupt line in normal operation. 5) TFT_eSPI is a very inclusive library, but you will need to alter it unless you have a board and pin setup combo that matches one of the many examples. This is not documented well. I recommend taking the SetupX_Template.h file in the User_Setups folder, configure it according to the comments in the file, save it as a new filename, and then you only need to change a single line in the standard library files from that point onwards, even if this library gets updated in the future. Then you can either copy this custom name file to the User_Setup.h file and overwrite the original. Or, everytime a new library version comes out, just edit the User_Setup_Select.h file to comment out the User_Setup.h and add a line to use the new file you created. Both ways work well. But expect that you will need to do this bit of customization to the library. 6) I2C address for the touchpad is as in the FT6336U library, address 0x38. You can also find example scanner sketches online which will confirm your board's touchpad I2C address. Overall, the display is a great value - nice and bright, large, and with a capacitive touchscreen that pretty much works out of the box without calibration. Review: Great 4.0" SPI Display with Responsive Touch and Excellent Connectivity - This 4.0-inch display is a fantastic option, especially if you're looking for something larger than the usual 2.5" to 3.5" screens. The 320x480 resolution provides sharp visuals, and the capacitive touch (FT6336U) is highly responsive and accurate with no calibration needed. Key Highlights: ✅ 4-wire SPI for the ST7796 display and I2C for the FT6336U capacitive touch—a great setup that ensures fast refresh rates and smooth performance. ✅ Use TFT-eSPI library support for video, though some customization is needed. ✅ FT6336U library for touch, which works flawlessly. ✅ 14-line ribbon connector with labeled pins—a fantastic inclusion! My dev board had all the display pins lined up but not the touch, so I had to use the ribbon to connect the touch functionality while still mounting the display. The fact that they included the ribbon cable is a huge plus. ✅ SD card slot (though I haven't tested it). If you're looking for the best 4-wire SPI screen with great refresh rates, this is the one to get. Highly recommended for anyone needing a solid display. Comes with documentation (better than most), but is still confusing. Just follow the advice of the reviews. 4.5 stars (rounded up to 5). Not perfect, but I haven't seen any better SPI displays. ## Features - 3.5-inch color screen, upgraded to use IPS full-viewing panel, 320x480 resolution, 300cd/m2 brightness and up to 16.7M RGB colors to ensure excellent display effects. - Newly upgraded to a capacitive touch panel, the touch is more sensitive and precise compared to the resistive screen. - On-board level conversion circuit, compatible with 5V and 3.3V MCUs. Adopt 4-wire SPI serial bus to save I/O pins. - The input supports 2.54 pin header interface and FPC extension interface, and comes with a micro TF card slot for easy storage expansion. - Provide rich sample learning programs (ESP32/STM32/Arduino R3&Mega2560/C51/CH32), provide underlying driver technical support, and update the information online. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CMD7Y55M | | Best Sellers Rank | #24,288 in Electronics ( See Top 100 in Electronics ) #616 in Computer Monitors | | Brand | Hosyond | | Built-In Media | 1 x 3.5 inch touch screen, FPC cables, Plastic protective box | | CPU Manufacturer | Raspberry Pi | | Compatible Devices | Arduino R3/Mega2560, ESP32, STM32 | | Connectivity Technology | I2C | | Customer Reviews | 4.0 out of 5 stars 122 Reviews | | Included Components | 1 x 3.5 inch touch screen, FPC cables, Plastic protective box | | Item Dimensions L x W x H | 3.85"L x 2.18"W x 0.51"H | | Item Weight | 3.5 ounces | | Manufacturer | Hosyond | | Mfr Part Number | H029-A | | Operating System | ESP32 | | Processor Brand | Raspberry Pi | | Processor Count | 4 | | RAM Memory Technology | LPDDR3 | | Total Usb Ports | 1 | | UPC | 741421390461 | | Wireless Communication Standard | 802.11bgn | | Wireless Compability | 802.11bgn | ## Product Details - **Brand:** Hosyond - **CPU Manufacturer:** Raspberry Pi - **Connectivity Technology:** I2C - **Included Components:** 1 x 3.5 inch touch screen, FPC cables, Plastic protective box - **Operating System:** ESP32 ## Images ![Hosyond 3.5 inch 320x480 IPS Capacitive Touch Screen LCD Module SPI Serial ST7796U Driver for Arduino R3/Mega2560 - Image 1](https://m.media-amazon.com/images/I/61BAXMByYkL.jpg) ![Hosyond 3.5 inch 320x480 IPS Capacitive Touch Screen LCD Module SPI Serial ST7796U Driver for Arduino R3/Mega2560 - Image 2](https://m.media-amazon.com/images/I/61Fja+NVw-L.jpg) ![Hosyond 3.5 inch 320x480 IPS Capacitive Touch Screen LCD Module SPI Serial ST7796U Driver for Arduino R3/Mega2560 - Image 3](https://m.media-amazon.com/images/I/61sSNLO1WrL.jpg) ![Hosyond 3.5 inch 320x480 IPS Capacitive Touch Screen LCD Module SPI Serial ST7796U Driver for Arduino R3/Mega2560 - Image 4](https://m.media-amazon.com/images/I/71ktCFDmByL.jpg) ![Hosyond 3.5 inch 320x480 IPS Capacitive Touch Screen LCD Module SPI Serial ST7796U Driver for Arduino R3/Mega2560 - Image 5](https://m.media-amazon.com/images/I/71K8g+nln0L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Recommended Drivers Work *by S***. on December 17, 2024* This is for the 4" 320x480 capacitive touch display with ST7796s.
