For a couple of days now I have been trying to get some visuals on a ILI9341 LCD screen.I'm working on a STM32F723E-DISCOVERY board. The LDC screen works with an 8080 controller. According to the manual of the device the internal IM bits define wethe...

I'm working on a course and until now all my examples worked fine using HSI as the system clock. But now I'm trying to get an ST7735 screen attached to SPI to work. The screen screen seems to require its hexadecimal instructions bitwise and the param...

A while ago I received an STM32 discoveryboard as a gift, after I told some people on a fair that I'm a software engineer. Because I'm allready experienced in C/C++ but new to embedded software engineering, I ordered a course. Now I get stuck on the ...

I just found out that I used HZ_5_SIG_LEN in the declaration of ReX[], where I should have used KHZ_15_SIG_LEN.Replacing this did make the program work without the obsolete printf("%f\r\n", 0.00001f) call. Nevertheless it still doesn't make sense to ...

Concerning the MISO line, I assume FRLVL would not increase if there would not be anything coming in.

Well, here's what I've got:This is my SPI init:void MX_SPI2_Init(void) { hspi2.Instance = SPI2; hspi2.Init.Mode = SPI_MODE_MASTER; hspi2.Init.Direction = SPI_DIRECTION_2LINES; hspi2.Init.DataSize = SPI_DATASIZE_8BIT; hspi2.Init.CLKPolarity ...

I did some more research on the Datasheet by searching on V12, VDD and Voltage Regulator and found some more usefull information afterall.V12 as mentioned in Table 16 "General operating conditions", the output on Vcap1 and Vcap2 stands for the intern...

SPI issues while trying to communicate with ILI9341. Only 0 comes in over miso and FRLVL decreases without reading from the dataregister.

Question regarding power scale mode and frequencies in RM0431 and DS11853

Program flow gets stuck. Why doesn't CC1IF Capture/compare interupt flag gets set, while debugging the next program on my STM32F723E-DISCOVERY?
