Can't find alternate funcions description on the Port C on STM32L051x6 x8
Reading the datasheet, on the Port C are reported several alternate functions. But the descrption of AF it is only for port A and B. Is it possible to have the AF descrption for the Port C too? Could take quite a long time to guss the correct mux.Tha...
I need to send 2 bytes over the I²c bus with a STM32L432 as slave and a Raspberry Pi as master. But the clockpulse of the SCL is to wide.
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...
can we trigger a Flag when the HAL_UART_Receive_DMA function no longer has any character for a long time
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...
[STM32F103] CAN_RX0 and CAN_RX1 interrupts stop working if I power board using USB cable.
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...
Using flash algorithm from F103 for F405
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...
Resolved! Shutdown mode for RTC
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...
NUCLEO-F401RE with Rasbperry PI - Virtual COM port for Serial Communcation not showing
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...
Resolved! is this the same IWDG with window enable and system WWDG???
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 ...
ADC in low power run mode measure same numbers.
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...
