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...
// 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...
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= ...
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...
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...
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...
Hey together,I have a question regarding MPU settings for an external QuadSPI Flash. We have a project where the full application code is placed onto the 4MB Quad SPI Flash memory W25Q32JVSIM. We have set up the QuadSPI in MemoryMapped moded and plac...
HiI launched a capture and sensitized the interrupt to both edges.I want to recognize each edge when intraoperating.I mean, to find out which edge was intraverted?I use micro stm32f407vgt
Hi,I am a newbie to STM controllers but I have worked on Arduino and Pi. I am thinking of working on STM because I have read that it supports multi threading, means we can perform multiple functions at the same time, as in high level languages. So, I...
