I did check the reference manual, but it was not stated. I have also seen in an image the same core has different counts of UART. Hence I am a bit confused.
We need to replace an end of life ARM 9 based SOM and I could use some advice on what ST Micro MCU would be a good replacement. The requirements that seem to be driving the choice are low power, 9 or more UART/USARTs, 2 or more I2C, at least 8 Mbytes...
I am using STM32F405xx and Cube IDE environment to evaluate my app. A layered CAN communication is requested. At this point, there are three layer to build this architecture. 1. 1.Layer is HAL library for CAN provided by ST and CubeMx: can.c and can....
We created a design with a STM303RET6 (lqfp64) microcontroller. For the first prototype pcb's we need 5 of this type microcontroller. But the problem is that no one can deliver this item (e.g. Farnell, Mouser etc). They don't give any explanation why...
I am working with the STM32F769 microcontroller and I want to generate a pulse on PE14 that is "a few" milliseconds wide. My SystemCoreClock is 216 MHz and my timer, TIM1, is hooked up to the APB2-bus, which is clocked at 108 MHz. My code looks like ...
I already have a STM32H735G-DK board for the workshop on 25th March and therefore do not need to order it.Today I have received email with the following ():"..we have allocated your seat to another participant."but I already have development kit.
Hi,I'm having some hard time setting up my STM32F303RE Nucleo board for using the ADC.What I want to achieve is...scanning 10 sensors (each connected to a GPIO pin on ADC2) in sequence three timestransferring the data using DMA to a buffergetting cal...
Hi,I'm using the STM32L4R5AG MCU with 4MHz MSI clock.I want to use I2C in fast mode (400kHz).The PCLK for I2C is also 4MHz from the MSI directly (in my application, I don't want to use a PLL).In CubeMX for 4MHz PCLK, if I select fast mode, the TIMING...
I have a Pi that sends data to the MCU via SPI. I have the SPI running in DMA circular buffer mode on the MCU. In the TxRx callback, the data from the Pi is processed, and then the motors are turned ON/OFF, etc. This works, however, each time the Pi ...
