i'm using STM32F030K6T6 microcontroller GPIO in open drain mode, i use external pull up res. by value 47k to VDD=15v while supply voltage for STM is 3.3v, the reason is that i wanna make a switching signal with 0v and 15v in output pin by the input 0...
Hi. I'm having trouble with integer interpretation for DFSDM. From the RM:> The offset correction allows to calibrate the external sigma-delta modulator offset error. The user configures the offset register with a signed 24-bit correction, and this r...
Hello All,I have an intresting issue that came up. But I am not sure if I understand it. In the clock configurator, I gave the usart mux a 100Mhz clock for the uarts and set up the baud rate for 115200K. Once I started sending data, I noticed that...
I have a very basic 8-bit parallel line on pins PC0-PC7 with its clock on PB6. The MCU is a 411RE, I'm using STM32CubeIDE and HAL libraries.I've read AN4666 but the examples provided are written using an obsolete library, not HAL. But I understood th...
Hi guys,I'm currently working with Standard CAN. The maximum data length of each frame is 64 bytes. In HAL library, I see DLC parameter is limited from 0 to 8. So that means, I can only transmit 8 elements of an array (8 bytes for each element). In o...
My goal is to start ADC conversions a deterministic amount of time after raising a GPIO.Since the ADC clock is slower than the instruction clock, the instruction to set SWSTART can occur in between ADC clock cycles. I currently have the ADC clock set...
I am using stm32f767zi nucleo board and they HSE clock input is coming from st link debugger which according to data sheet of the board generates an 8 MHz MCO signal which is fed into the OSC_in pin. I have configured HSE bypass as the clk source for...
I am working with an STM32F405 and am attempting to use a page of flash to store ~1K of persistent data that will be seldom written and often read (device serial number and calibration data).I have been trying to reference sample code and a few other...
Hi,I am currently implementing a guitar effects pedal using the STM32F446RE and the PCM3060 as my CODEC.I have gotten everything to work, except when I try to adjust the following parameterscf0_lim = (int)(time*l_CB0);cf1_lim = (int)(time*l_CB1);cf2_...
Hi,We are working on a STM32 project based on sample_azure_iot_embedded_sdk_adu project. The board is B-L4S5I-IOT01A. At the moment, we are implementing the OTA. The board is able to download the firmware bin file, however it is stuck at the function...
