Resolved! STM32H7 DMA not transferring correct values into TIM15 CCR1 register, why?
Hi everyone, I feel like I am running out of options as to why this is occurring as the RM isn't that accurate to setup DMA + PWM using Timers. The goal is to use TIM15 as a PWM generator running @ 800kHz running until 24 pulses are outputted and the...
Configuring Idle State for Timers
HiI have successfully managed to configure and implement a TIM4 channel 1 as a PWM channel and connect it to DMA. Upon disabling the DMA after a transmit, the output goes high - this was the default and is desired. However, I've taken this further to...
Resolved! Is there a maximum speed with DMA? (F446RE)
Hi, I am using DMA to generate an arbitrary waveform on PIN PA_8 using TIM1_CH1. My HCLK is at 180MHZ, APB2 timer clock at 180 MHz and APB2 peripheral clocks at 90 MHZ.Even though having this clock, when comparing the oscilloscope and the value of AR...
2 bit RTC->DR problem for STM32F767 (corrected title)
I am using STM32F767, unfortunately I have a problem with the DR register area in the RTC. Exactly the problem is with the 10th and 17th bits of this register. Setting "1" means that I am not able to change these bits to "0". Only resetting the BDCR ...
Resolved! STM32G030K6T6 is not programming!
Hello,I'm working on a small scale project. In my earlier design, I've used the STM32F100x series. Now as the STM introduced a new set of controllers, the STM32G series ( which is less in cost and much higher efficiency than STM32F series), I've migr...
How to use printf() to output to UART
I have been using printf() to output to UART for many years on a STM32L052All these projects still compile and printf() to UART, no problem.I started a NEW project with CubeMX, but now printf() does NOT print to UART.I use the same int fputc(int ch, ...
MT29F128G08 NAND FLASH with NUCLEO-L496ZG basic driver help
I am not much of a software/firmware developer, but i need to get a basic Driver working for NAND flash device "MT29F128G08AJAAAWP-ITZ" working on a "NUCLEO-L496ZG".I have the device wired up to the eval board, and need to build a basic drive to writ...
What is the correct maximum FMC clock on a STM32F767 ?
Hi, I am currently working on a display driver board, with a STM32F767. And I would like to use the FMC with a SDRAM.My problem is that the MCU is clocked at 216MHz, the SDRAM max clock is 133MHz, on the F767 documentation, it is written that the max...
Is there any board which can support more than 30 MHZ Toggle frequency on GPIO and Parallel processing.?
Currently we are using Nucleo F746ZG controller with 216 MHZ frequency.We are able to get high toggle frequency on GPIO with this board.Now we want to shift to Micro Processor for parallel processing.So is there any Better Controller/Processor availa...
