Heyho,I'm using the H733 (custom board) / H735 (eval kit) with Infineon's HyperRAM S70KL1281 / S70KL1282 at 100 MHz for some time now, all working great, except for one thing that is very annoying:the data throughput from / to HyperRAM seems to depen...

Heyho,using all SAI blocks on H723 / H733 / H735 with stereo audio ADCs via DMA, working smoothly as long as both channels are used.Now I wanted to implement turning off single channels, and I thought I could do that with the SAI / DMA settings.I jus...

Heyho,I'm using a H733 with both SAI 1 and SAI 4 with SAI 1 as I2S clock master to get 8 synced audio channels.Audio clock comes from I2SCKIN, this is used for SAIs and I2S.Problem: because of the fixed oversampling ratio (256 or 512) of the SAI, I h...

... leads to "funny" results:STM32L011 with 16 kB of flash, HAL inits and LED toggle in main, DEBUG, no optimization:93% of flash usedI had not expected it to be that bad! :grinning_face_with_sweat:Okay, I will probably not use too much HAL, will use...

For a simple DC output without DMA, the F7 DAC is quite simple to use.So check if the DAC peripheral clock is set and enabled, if the GPIO is set correctly.I suggest to use some UART IO to check registers and change DAC level. void DAC_Init(void) { ...

After the basic ETH MAC setup (GPIO, ETH DMA SW reset, MDIO), the first thing I do is giving the LAN8742A a software reset via BCR register, then wait a little for the PHY to recover.Then I write the enable bit for auto-negotiation, then get into a l...

1. read the datasheet of WM8904, which is not a product from ST2. working source code... you're not telling us which STM32 you are using and how it is connected to the DAC

Then check if your router has a DHCP server that can be activated.

It was actually @Andrew Neil who said first that flash must be erased before writing, so maybe mark his answer as solution.Although I guess "in the end it doesn't really matter", as who sang? ;)
