Resolved! Please, where can I find a "key_pair_generation" example code for the Discovery Kit B-L4S5_IOT01A? (STSAFE)
I tried porting the example code has been done for the Nucleo board to the B-L4S5_IOT01A but I get STSAFEA_COMMUNICATION_ERROR as result. SEE BELOWKey pair generation demonstration: 1. Generate key pair through STSAFE-A's private key slot 1 => Use ...
STM32L4R5 UART DTR/DSR hardware connection
Hi, I'm trying to connect my bluetooth IC Ublox ANNA-B112 to STM32L4R5 using USART line. The bluetooth IC requires DTR and DSR line but it doesn't seems like STM32 has these 2 lines on the manual. Is there any ways to implement DTR and DSR on STM32?
Timers break and clear behavior in general
Hello. I can't fully understand break and clear funtionality of timers on STM32. In read dasheets and tryed various options for break and clear inputs, but in general it worked in a similar way:It puts timer output to predefined state untill it overf...
How to synchronize multiple microcontrollers
I have multiple devices with stm32L5 mcu playing led animations and connected via RS-485. However, when I send a command via RS-485 to start led animations, they become asynchronous. I want to use an mcu clock as reference and send it to all others m...
STM32 turning DMA on and gives odd results
I am trying to dynamically start and stop PWM and DMA which are triggered by a timer with this code: void CAM_startLineTransfer(CAM_HandleTypeDef *cam) { // init DMA while (cam->requestDataTimer->Instance->CNT <= 60) {} HAL_TIM_PWM_Start...
Output Compare stay on actual voltage level
I need an output compare trigger output with toggle function, and the start/stop should be on the correct frequency. Start is ok now, Stop I like to stay on the actual volatge level (high or low)The problem now I face is when I turn off the timer wit...
Performance varies notably when the code alignment changed by 2 bytes?
I am running Thumb-2 instruction code on STM32F750N8.I am seeing non-negligible performance number variation depending on whether I insert one NOP right before a tight loop (and changing the address of each instruction by halfword). Other parts of th...
Resolved! Why RXNE is automatically reset after write data to DR register, even I already set the FRXTH to 1
I have a problem where even I already set the FRXTH to 1, the RXNE will automatically RESET after the SPI write data to DR register.I check using DEBUGGING MODE:In main(), I already SET the FRXTH based on the reference manual below: Then, after I wri...
