Hello there
I recently got this new IR Remote from ebay. it uses a vs1838b IR sensor and after digging for a while it seems like I need to setup PWM to read signal from it with my stm board.
However all my attempts failed.
Anyone can help my write a simple code to read the sensor input and maybe...
It turned out that the driver IC is not ST7735 , but it is S6D02A1 from samsung.
I found the library for arduino https://github.com/sumotoy/TFT_S6D02A1/ and I'm trying to convert it .
I'm struggling with this code the most
static const uint8_t PROGMEM // Multiple LCD init commands removed...
@Easyrider83 Amazing !! Adding the resistor made the TFT backlight work like a charm !!
I'm stuck though with converting the arduino library for the S6D02A1 for my STM32F4 https://github.com/sumotoy/TFT_S6D02A1
Any help ?? I appreciate your support !
Ok , I just learnt that the pne I have uses samsung s6d02a1 controller not st7735 ... but the modules are very similar
@klaus
I'm trying to interface this to an STM32F4 .. i have to convert the arduino library... Anyway to verify if my code does not work or is it the TFT itself ???
I thought...
Re: 1.8" TFT Not working
These cheap modules from ebay come with not much info about them.
Obiouvsly there is always the datasheet of the controller itself but I beleive the backlight has nothing to with it ??

Thank you for your quick reply ,,, The code looks neat...
I recently got a new 1.8" TFT LCD .. I learnt that it's using ST7735 IC as a controller..
However I'm not even able to get the backlight to work.
The pins goes as:
-RST
-CS
-D/C
-DIN
-CLK
-VCC
-BL
-GND
I Connected the BL to both 3.3V and 5V but no luck.
Anyone experienced with these displays...
I just got a pickit2 from one of the nearby stores, to find out later on, that the PIC32MX170F256 I have is not supported by the programmer.
Is there anyway I can add it to the supported device list ?
Or there is no way around it.
Thank you :thumbsup:
Hi there , I'll be asking quiet an odd question but is it possible to program a PIC Microcontroller using an ST link or stm32f4 discovery board in general ??
If this has been asked before or was a blog post about this anyway please let me know.
Many thankx !!
Hello there, I wrote this simple code to test freeRTOS on my stm32f4 discovery , the code compiles nicely and give no errors but BlinkLedTask does not Blink the led on the board.
#include <stm32f4xx.h>
#include <misc.h>
#include <stm32f4xx_rcc.h>
#include <stm32f4xx_usart.h>
#include...
Definitely I have 32K RAM free but how so I sort the data during sending or within the RAM exactly in code please , thank you.
BTW is the TFT controller okay with what's so ever the SPI frequency is ?
Hi there , thankx for replying. Based on what you advice and what I have here, I made something like this:
int Cnt = 128 * 128;
int i = 1;
SetAddrWindow(0,0,128,128);
while (Cnt--) {
writeData16(mainscreen[i]);
i++;
}
But I got 2 small issues:
-The image is rotated now , like in...
Hi there , thank you for taking a look at my thread.
The question is "Does increasing the SPI Frequency Increase the TFT Bitmap loading speed ? ". I have my bitmap stored within an array and it works fine but the loading of the image takes about 2 secs.
Is it also possible if I would change the...
Hi there, I just came across your question and thought you're having a situation similar to my current one. I'm trying to build a simple wearable using an ARM MCU and thought so far results I'll try to answer. Personally I used the STM32F4 discovery board , it's a real powerful Cortex-M4 dev...
