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...

Start by sending small and simple text files with some readable ASCII.Then increase the text file so that it is sent via multiple packets.If that's working, try with bin files.Use Wireshark to check packets, and UART output on the STM32 side.

No, you don't have to split anything, that is what the browser does for you.On the STM32 side, you have to store the payload of each packet. Only the first packet has this extra length and file name info (plus already some data of the bin file).

POST is a http "method" using TCP, so maximum single packet size is usually having a maximum data size limited by TCP to 1460 bytes.Thus, anything larger must be sent with multiple TCP packets.The size of these packets depends on your PC settings and...

If you got the header of the POST message, then you will surely get the rest.Read, check, think, try...Check which httpd_post_* functions are called from httpd.c, but NOT implemented. Then search the web or build your own.
