Can you drop in an STM32F427IGT6 on a board with an existing STM32F407IGT6?
I am running out of SRAM on a project with an F407 and an investigating using an F427. My basic question is does anyone know of the issues with doing this? I have already read through the migration document (AN3364) and am continuing to investigate.I...
Using bxCAN HAL; STM32F072
To begin, I have a question regarding the CanTxMsgTypeDef and the CanRxMsgTypeDef configurations (listed here.)My question is, how to properly initialize the parameters :uint8_t Data[8]; of CanTxMsgTypeDef and uint8_t Data[8]; CanRxMsgTypeDefI can lo...
Help with odd STM32F765BI QSPI behavior? We're seeing what looks like an extra or spurious read transaction.
We're seeing what looks like an extra or spurious read from the QSPI block on our STM32F765BI. As yet, we're not able to pinpoint the cause and could use some ideas of where else to look. Sorry that this gets a bit long. Background:We're using the...
Resolved! Jump from one Application to another STM32H743
Hi all,I have a problem when jumping from one application to another within my new STM32H7 system.Explaination: All my systems can be updated via my own bootloader (running on 0x800 0000) application, which communicates via USB port with a PC to my s...
Resolved! RM0395, STM32L412 and ADC12_CLK
Hello,RM0394 Rev. 4 chapter 16.4.2 clocks should note in a preamble or something similar that Dual clock and ADC12_CLK is not available on STM32L412. Reading through RM0394 I conclude that ADC clock is HCLK fixed on L412, but I don't see it stated ...
Can anyone tell me if the STM32F101 and STM32F103 are interchangeable?
One of our customers has replaced an STM32F101R8 in the field with an STM32F103 and cannot get the unit to power up. My question is with the same code and the same PCB will the two processors function exactly the same?Thanks
RM0394: Mismatch RM0394 and stm32l412xx.h
Hello,while RM0394 talks about CH18SEL and CH17SEL, in16.7.2 ADC common control register (ADC_CCR)stm32l412xx.h only knows ADC_CCR_TSEN and ADC_CCR_VBATEN .While the names in stm32l412xx.h are know to me from other devices, the names in RM0394 are ...
9 bit UART and DMA
Posted on September 18, 2017 at 07:46Hiya,I'm using the UART in 9 bit mode, with the 9th bit being used as an address indication.I have a version of this working well with 16 bit DMA transfers. Ideally though I want to use 8 bit DMA (byte wide) as a...
Problems with CAN on STM32F072RB
Hi, I'm trying to implement CAN on the STM32F072RB and I think I have added all the neccesary files. In stm32f0xx_hal_conf.h I have defined HAL_CAN_MODULE_ENABLED, but in stm32f0xx_hal_can.c it is not recognized. The question is that when compiling e...
