In my software, I usually extend the 24bit SysTick handler to 32bit with the tricks shown in the code segment below. Using such a do-while construct as shown in "GetSysTickCompleteVal" I usually prefer for the fast access to volatile interrupt data, ...
i am using STM32L4S5 series controller which contains 2MB flash. recently I got a problem like Read out protection activated. Because of that i am not able to read write as well mass erase also. And then i read the options registers from 2 boards (on...
Thank you for new I2C interface, this really is supergreat compared to the cumbersome STM32F4 solution. My new STM32H7 I2C code is only about 20-30% of the STM32F4 version - I use a state machine and needed > 10 partly extremely cumbersome states in ...
Hello,I have a very weird behavior...When trying to access external synchronous PSRAM.I see the clock and cs change only if I stop and starts stepping inside the while(1) loop below. When doing "go", there is no clock nor CS changes.I tried to add de...
Hi community,I'm using the STM32F072 Discovery kit (https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-mcu-discovery-kits/32f072bdiscovery.html).The ST-LINK/V2 embedded de...
How can I locate array in SRAM instead of DTCM RAM(128kB)?uint16_t array[320*240] is overflowed in H743ZI.Sytem workbench says <DTCMRAM overflowed by 25760 bytes>.I don't have any trouble with F429ZI.
I want sample 2 channels using stm32l011f3 mcu from ,PA0 PA1,the main function code is int main(void){ /* USER CODE BEGIN 1 */ uint8_t value_L; uint8_t value_H; uint8_t i = 0; /* USER CODE END 1 */ /* MCU Configuration--------------------------------...
The code in bootloader does unlock and lock wrp for certain blocks in both the bank of internal flash which corresponds to application code.Sadly these calls are done not at the beginning and end of the code but at different states in the code logic....
The starter microcontroller is STM32L041F6P7, and the application is a wireless sensor module (868Mhz, Fire / Water Leak / Gas Leak / PIR Sensors)).In the future microcontrollers can be used are STM32L053R8T6 or STM32L152RBT6.
The Marketing documentation and CubeExpansion Doxygen has some hints to the LoRaWAN use case.But the source files are not included./tmp/STM32CubeExpansion_STSAFE-A1xx_v2.3.5$ grep -ri lora Binary file Middlewares/ST/STSAFE_A1xx/Documentation/STSAFE-...
