Hello,I have struggled to use AT COMMANDs for communication between ESP8266 and STM32F4.I should use ESP8266 as non blocking mode .Because my main project is FIRMWARE OVER THE AIR. 1)STM32 GETs the datas of new code via ESP8266 using 'AT COMMANDS'.2...
I'm trying to program i2C1 interface of STM32L151 with 3-rd side tools - Algocraft WN programmer.The sequence of operations attached in the DOC file.After these operations the START bit does not generated (checked by scope) and MASTER bit doesn't app...
I need to use the ETM on a STM32H753 but without debugging tool. The idea is to record the execution trace all the time, and when the firmware encounter a critiical issue, output the trace to an external tool or program it to flash for later analysis...
Good morning!I have the following problem with STM32L100RCT6 chip.After entering into USART BootLoader mode and resetting MCU into the standard mode via NRESET Pin and BOOT0 Pin Pulled Down, the current consumption in STOP MODE increases by 200uA. Af...
Posted on February 01, 2018 at 21:39Hello!The HAL CAN driver for the STM32F4 got reworked lately (december 2017). I try to port my code from the old to the new drivers (compatibility break). There is a brief driver description in the update history ...
I have stm32f4 discovery board(STM32F407VGT06) running at 168Mhz. requirement 1) i have to run a motor (AC synchronous servo - yaskawa ) by pulse and direction.for which i can use a timer in PWM mode with 50% duty cycle. relat...
Good day.The reference manual RM0033 for the microcontroller (in the Boot configuration section) states that "When the device boots from SRAM, in the application initialization code, you have torelocate the vector table in SRAM using the NVIC excepti...
Hi, I am synchronizing two timers, actually already succeed but I was stuck two days because the trigger output event TRGO of TIM1 was connected to OC4REF (and CCR4 was accordingly set).With this configuration I didn't receive a pulse in the slave tr...
I read TS_CAL1 and TS_CAL2 values from stm32f303vc and saw that TS_CAL2 is lower then TS_CAL1. Is it correct? I think this is mistake. I check the memory with Visual Studio in debug mode and saw the same values. Why is it so?Thank u in advance!
I've a problem with UART on Bluepill (STM32F103C8T6). Let's say that I need to send some string via UART periodically using Std Peripheral Library . Below I post simple code which 'propably' should work. What I know for sure is that devices (bluepill...
