I want to use N657B0 to drive VD55G0, and the camera side can already enter the Stream state. After I use the function HAL_DCMIPP_CSI_PIPE_Start, I track the variable csi_instance through single-step debugging and find that several bits in its SR1 re...
I have a STM32U595 and I use the RTC in binary mode.If an SSR underflow occurs during Vbat mode, will the SSRUF be set so after power recovery I can manage the interrupt ?
From my understanding all STM32N6 chips need a external flash chip and there's a static stage 0 boot loader. So if this is true is there any limitation's on the brands of flash or speed/address bit size limitations? With the previous stage 0 bootloa...
Hi Everyone,I am working on a project with TouchGFX. I'm working with STM32U5G9ZJT6 and I have an external RAM APS12808L-OBM-BA connected via HSPI (Fclk-hspi 100 MHz) in mapped mode. The project is working, but the image animation are not working wel...
In the RM0456 at 33.4.31 Oversampler it say:The division coefficient M consists of a right bit shift up to 10 bits, and is defined using the OVSS[3:0] bits in the ADC_CFGR2 register.But at 33.6.5 ADC configuration register 2 (ADC_CFGR2), it allow up ...
IssueHigher ambient temperatures cause communication malfunctions with XSPI memories.DetailsOur design is heavily adopted from STM32H7S78-DK which also has the same issue described below.The application uses memory-mapped mode for both Flash and RAM ...
Can somebody please help me. The code below is initializing the RTC. The clock works I can set and read time and date no problem. Somehow if I change these register: hrtc.Init.AsynchPrediv = 131; hrtc.Init.SynchPrediv = 10; It has no imp...
We're using the following circuit to measure a battery voltage @ 20 kHz for use in motor control.We are having some issues though, where the ADC suddenly starts measuring 0 V (0 in the data register) and gets locked in this state. In this state, we a...
In our project I use STM32H573VIT6 LDO uC. We have a problem with the PB14 pin. We use 3 pins for LED control (PB10, PB13 and PB14, see photo). The problem with the PB14 is that the LED lights up dimly without code initialization. If PB14 is initiali...
Hi,I'm attempting to write to an SD Card using a Riverdi STM32U5A9 display board. Since TouchGFX natively uses FreeRTOS, I'm attempting to keep it within FreeRTOS. Porting to ThreadX has caused it's own issues which I have in a separate thread. In...
