I need some help on configuring a transfer from external SDRAM buffer and LCD buffer (via FMC with Intel 8080 like interface).I've adopted the [MDMA_RepeatBlock_Rotation] as refernce example from the CUBE_H7 package.In this project for STM32H743I_EVA...
I had tried to compile a project with only a 64-point fft. But it turned out to be like"fft\fft.axf: Error: L6406E: No space in execution regions with .ANY selector matching arm_common_tables.o(.constdata)."I cannot believe it as I can run fft on bas...
Hi everyone:We tried the MCSDK and deployed it in stm32f407. But we got a problem, for example: We use the motor control GUI trigger the motor to 20k rpm.We press the stop button.The motor go into free run status.When the motor speed decrease and not...
Hello:There is a post on this same issue titled "TIM16 PWM signal generation...". The fix here was to set the AOE bit in the BDTR register. In that thread they were using LL.I am having a similar issue where I am unable to get the PWM output signal o...
Hi,today I stumbled across a problem, where I wanted to assign around 50k of RAM to FreeRTOS and I immediately got a linker error, because target ran out of RAM.I had a look at the datasheet and this says 48k RAM. I've been using a self-hacked-toget...
I am using STM32F407 on STM32F4 Discovery Board and the IDE i am using to program is Keil_v5. I am trying to transmit data using I2S communication protocol on I2S port 2. I used the System Clock Configuration tool provided by ST. The desired configur...
Hello,I would like to start a new design based on STM32H7x3.I need both CAN-FD channels. But the erratasheet from June 2018 describes a problem and the workaround is "use only one CANFD channel".Will there be a new chip version or workaround soon be...
Posted on November 15, 2017 at 10:48Hi,We are using Tianma’s - TM070RVHG01 TFT in our design with STM32F429 processor working at 168 MHz frequency. We are using EmWin Library on RTX operating system with LTDC support. We are statically storing th...
Hello,I would like to start a new design based on STM32H7x3.The STM32H7 Evalboard uses a dual voltage level translator between MCU and SD-Card. But this required some extra pins (DIR_0,DIR_1_3, CLK_FB, DIR_CMD) that I need for anothere peripheral.Cou...
The RTC wakeup interrupt uses EXTI-20. Unfortunately the HAL drivers do not properly enable the interrupt. AddingEXTI->IMR1|=(1<<20);after HAL_RTCEx_SetWakeUpTimer_IT fixes the issue
