In the code below I send 2 bytes with my STM32 (I've chosen a number higher then 255 (340) so it needs to send the data in 2 bytes) but on the scope I cant find this data. I guess it's because of the wide clockpulse and the Rpi expect an ACK. Instead...
I am coding on a stm32 a connection between UART1 and UART2. I would like UART1 to transmit the data rise by UART2 and vice versa (my stm32 will only be a gateway between a PC and an IOT), I do not know the size of the data that arrives on the two UA...
If powered otherwise, everything is OK.HAL_CAN_RxFifo0MsgPendingCallback is CAN_RX0 and HAL_CAN_RxFifo1MsgPendingCallback is RX1 right?I see that "USB low priority or CAN RX0 interrupts" are connected, but CAN RX1 should be independent from USB?Is it...
Hi,I am trying to use a flash write and read module written for the STM32F103 on an STM32F405.However the F103 deals with pages and subpages. Some algorithms depend on subpage size. The F405 has sectors, which I guess are the equivalent to pages, but...
Hello, I'm using the demoboard B-U585I-IOT02A with a STM32U5 microcontroller. Today, I'm using a RTC with an external battery placed before VBAT. But in order to reduce current consumption, I'm currently working on using shutdown mode in order to jus...
Hi, I've been working with the NUCLEO-F401RE board developing on windows. Everything has been going smoothly but I'm having issues now that I'm trying to connect it to a Raspberry Pi.On Windows, when connected, the STLink Virtual COM port shows up p...
I have working code for an STM32L0 device that uses Alarm A of the RTC to wake / interrupt at the desired minute interval. I now require the ability to wake / interrupt at the desired hours AND minutes time. Previously all masks were masked except fo...
Hello ~I'm studying IWDG concept. (STM32F769-EVAl)First picture is the block diagram of IWDG at reference mannuals (stm32f76xxx, stm32f77xxx). Second picture is IWDG parameter setting using Cube MX. Window register doesn't exist in block diagram. Is ...
Hi everyone,I have stm32L053R8 nucleo64 board. I'm trying to get adc measure in low power run mode. It's not working correctly in Lprun mode but when I try in run mode it's working. In Lprun mode I only get 2 values. Half of the resolution and full o...
I've been testing the internal temperature sensor on STM32 Nucleo-L452RE.Therefore, I am using the internal Macors as well as a self-build function to calculate the temperature. Both yield the same value, thus the same constant negative offset of rou...
