Resolved! What is the fastest adc sampling speed when using 4 adc's
HiI thinking of buying and STM32WB (P-NUCLEO-WB55 evaluation board) because of the fast ADC. I need to sample four analog signals with a rate of a few hunderd Ksps and store their values.what would roughly be the sample rate when using 4 adc inputs (...
Resolved! LRWAN2 Gateway will not connect to TheThingsNetwork
Hello, I'm facing a strange problem. I just bought the LRWAN2 package, connected the gateway to the network, one usb cable to power it and one usb to the st-link. I configured the packed forwarder to router.eu.thethings.network,1700,1700 and CH to U...
