I2C error handling
I am developing with STM32F030Cx, using CubeMX for the configuration. The application is basically a simple full cooperative scheduler (no RTOS, no context switching) that calls several "tasks" in a sequence. I am using the blocking functions of the ...
How to configure STM32H743 to reach maximum ADC sampling frequency? (3.6 MSPS or 3.6 MHz
Hi. I am just learning to use STM, this board was bought to me by my employer. Please, look at my clock config and code, and tell me, what is wrong. ADC clock is set to 36MHZ, ADC prescaler = 1, sampling time is set to 1.5 cycles, conversion time i...
Can I use STM32F103C8 in a Medical Device.
We have built a respirator prototype using a pic microcontroller, which has been tested by doctors and they are satisfied with the results, now we wanted to manufacture the product in a large scale and before that it needs to be certified for IEC 606...
big gap between CS and SPI transmit
// CS pin go low to select HAL_GPIO_WritePin(GPIOB, GPIO_PIN_6, GPIO_PIN_RESET); HAL_SPI_Transmit(&hspi1, (uint8_t *)spi_buf, 3, 10); // CS pin go high to release HAL_GPIO_WritePin(GPIOB, GPIO_PIN_6, GPIO_PIN_SET);I use the above code t...
STM32L432kc
Hi guysI'm using the nucleo STM32L432kcFor the purpose of measuring fluide conductivity i need the following actions.- Generate a PWM1 signal with a frequency between (100Hz_ 10KHz) with a fixed duty cycle of 50%- 2 DAC signals DAC1= 1,5V+ VextDAC2= ...
Resolved! Hello! I'm using STM32L422 and I'm having trouble with setting up the PLL above certain frequencies. Are there any specific configuration requirements when setting up PLL at high frequencies?
I use 8MHz crystal as the input for the PLL. I'm using a timer and a LED to verify frequency, aka the LED should blink at 1Hz. Everything works fine until 48MHz, after which the STM seems to fail - led doesn't blink and the debugger does not know wh...
On stm32h753 eval board, which uart is connected to ST-LINK version 3?
I would like to be able to write debugging messages to a serial terminal. Is there sample code that does this? Is there something I need to know about setting up clocks that is special for ST-LINK v3? How does one know which uart is connected to ST-L...
STM32L071 can't disable SysTick
Hi,I've got a problem with STM32L071 and SysTick. I got a two programs written for this MCU - bootloader and the main app. The bootloader uses HAL dirven with SysTick. Standard SysTick_Handler() function is responsible for handling the interrupts com...
