I will graduate in two months. During my postgraduate study, I got a lot of development boards. I probably won't touch them again. I sell them on the forum. Support E-coin transactions and keep updati...
pythoncoder In the micropython eeprom driver library, new support for PSRAM has been added.Multiple devices can share a single SPI bus to form a single logical RAM.
It is possible to use the RAM as a ...
Has anyone used vsc8201 for development? I can't find a way to set it for hardware filtering. I want to use it to receive all packets (including all packets in LAN). Now I set it to promisc, but it do...
I am a beginner in microcontrollers and have seen many C programs related to ds18b20. When reading and processing data, the last step is to multiply by ten and then round off. I don't know why. I hope...
