I am confused about the limits of the FT pins on this MCU. I think I understand the maximum voltage on an FT pin except FT_c is Vdd + 4V as long as no pulls are enabled. So with 3.3V Vdd the max voltage on most FT pins will be 8.3V is that correct? I...
Is the internal bootloader on the STM32H723 DO-178 certified? It just dawned on me that the whole line of CPUs might be disqualified for aircraft use because the bootloader code "flies" with the aircraft and all such code must be certified to the l...
Hallo all:I want to implement a generic counter to count the number of impulses on an input, but after debouncing.I guess that mechanical switches for human interface purposes need a debouncing in the milliseconds range, say 1 ms to 20 ms. My Systick...
I am trying to use a G431 as an I2C device (slave). Unfortunately it can be made to latch up rather easily, getting stuck with an endlessly triggering I2C interrupt. It appears to be a flaw in the HAL code where it doesn't clear the interrupt flags, ...
CubeMX-generated code gets stuck on HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED) using IDE v1.17.0 and FreeRTOS. RTOS is using SystemCoreClock. HAL Tick is using TIM17 with a priority = 14 (Higher than SysTick Timer.)Made AdcTask highest pri...
Hi,I am using a Nucleo32 F411RE to control a 2.9inch flexible E-Ink raw display panel from WaveShare. I use their circuit and a copied version of their code they have on their website. The code sends SPI commands over SPI1 of the F411RE and controls ...
Hello ST Community,I come from the NUCLEO-F401RE, where I could simply build one application image, flash it into internal Flash, and run it immediately—no secondary bootloader ever needed. I recently upgraded to the NUCLEO-H7S3L8 to leverage the hig...
Hi, I'm trying to connect a high speed ADC to an STM32F7. I have chained two timers to generate the necessary convert and read pulses to the ADC. Its output is 16 bits that are all connected to the same gpio block. However I would also like to setup ...
Hi, I'm using the ADC1 of the STM32H563 and I'd like to configure an offset (64) for all 12 of my analog channels. I'm using GPDMA1 to obtain an array of 1200 values at 100 kHz. When I configure the offset (before starting the conversion), I don't ...
HiI'm planning to make a digital mixer that takes 4 analog audio input channels (2x stereo), processes them with digital effects, in 24 bits, and outputs 4 analog audio channels. I’m trying to figure out which chips may be compatible for my project. ...
