I try to build a RS232 conversation via the sub-D port on my STM32F769I-EVAL to my Computer.
Hi everyone.I have been struggling with the connection with RS232 between the sub-D port on my STM32F769I-EVAL and my Computer for sometime . I did follow the tutorial insturctions (https://www.youtube.com/watch?v=tMS5IOfZXyo) step by step but I don...
How can I generate timer interrupt for 300 sec STM32L0 series?
HelloI have used Nucleo-L031K6 dev kit.How can I generate timer interrupt for 100 sec/500 sec delay?
Resolved! DS12288 Rev 4 - Typo in Table 12, page 67
In the first row - corresponds to "Pin Number" D2 for WLCSP81, Alternate functions column, it has:TIM3_CH4,RTIM1_CHE2It should be:TIM3_CH4,HRTIM1_CHE2I emphasized the "H" to make it clear that it is missing. I think this is the only place I saw this.
Resolved! How to write to SD card over 4G address by HAL?
Hi All,I am using STM32H7 to write the SD card. The SD card is 16GB. But when I call HAL_SD_WriteBlocks, I found it only accept under 4GB(uint32_t) address. Here is header declaration. HAL_StatusTypeDef HAL_SD_ReadBlocks (SD_HandleTypeDef *hsd, ui...
Using other pins of TSC group as GPIO or Alternate Peripheral Function
Hello All,I have a doubt. As we know each group of the Touch Sense Controller (TSC) is made of four IO pins. One is used for sense capacitor, leaving behind three for touch sense electrode usage. But if we need to use only one or two of these as an t...
What is the min/max skew on the counter outputs for the STM32F107RC?
Hello all, I looking to use a STM32F107FC as a digital waveform generator. The system clock would be 28MHz and so would the APB bus feeding the timers. I plan to have TIM4 drive an output with a 14MHz clock signal and act as a master for TIM3. TIM3 w...
STM32F3 HSE crystal startup issues
We are using an STM32F303VEH6 on a custom design. We are using a ILCX13-FF5F10-16.000MHZ crystal oscillator. We have the PLL and clock gain setup to generate a 72 MHz CPU clock. On some CPUs we have problems where the CPU doesn't appear to try and st...
On the fly OTA example
Hi,I am working on STM32 with Quectel GPRS module.Now I have to implement OTA without using any external flash or SD card.Is there any example for GPRS based OTA without using any external memory to park the bin/hex file and program the MCU flash on ...
