i got a stm32f4 and wrote some code to it, then tried to run openocd and got this error my openocd.cfgnote - i reflashed the stlink a couple of times and changed it to jlink(and then back to stlink) so that might have something to do with it.would v...
I do not see any information on the datasheet or reference manual, how is the TRACECLK in STM H5 (particularly 563 if it matters) derived ? Is the TRACECLKIN SYSCLK or FCLK ?
Hi everyone,I’m working on a project using an STM32 microcontroller (STM32H745IITx), and I’m trying to set up a DMA transfer for an external 12-bit, 20 MSPS ADC with a 12-bit parallel interface. On my custom board, the data pins of the ADC are route...
Hello,For STM32U5A5QJI6Q, can we use a Normal SPI Flash instead of Octal SPI Flash? We are asking this question as we want to use Normal SPI Flash to reduce size and cost.
Hi,Recently I started working on stm32F07 microcontroller. I am trying to read sensor value using ADC.Issue: ADC value is keep on changing randomly(means its not holding value).Below is my code. Please refer it and help me to figure out the issue.Clo...
Posted on May 11, 2018 at 01:27 Hi ThereI was looking at AN4661, pg 45 where the signal routing guidelines for SDMMC is given. It has the below bullet points when it comes to skew The skew being introduced into the clock system by unequal trac...
Is there a proper way to implement a float value? When i try to declare a float variable and debug via the variables tab and or live expression (global variable) I keep getting incorrect values in some instances. I have included the float library and...
Good morning, We've been working with the USART connectivity on the H7S3L8 board, since the new CubeMX update added the missing "Hardware Flow Control (RS485)" option :However, after connecting a sensor that we know is responding (tested through a di...
Hello STM Community,I am currently working on a project using an STM32F407 microcontroller with LWIP and MQTT to connect to Azure IoT Hub on the secure MQTT port 8883. I am encountering an issue with the mbedtls_x509_crt_parse function when trying to...
Hello everyone,I'm currently working on a project where I'm interfacing the KSZ9893 Ethernet switch with an STM32F427 microcontroller. The setup uses the RMII interface for data communication and I2C for management.Issues i am facing:1.unable to ping...
