How to drive the VD55G0 in N657B0

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...

Resolved! Any limits on flash selection for STM32N6

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...

Using external RAM with STM32U5G9-HSPI

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...

Resolved! RM0456 discrepancy in ADC oversampling right shift

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 ...

Resolved! STM32H7S7L8H6H XSPI instability

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 ...

ADC "shorting" analog input to GND

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...

Resolved! STM32H573 PB14

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...
