I've been using an 18f1330 at 32 MHz, but I'm having a lot of trouble with reliable communications at 9600 BAUD. The ESP8266 does not seem to offer slower speed, and I'm losing bytes occasionally. The code is using DT_INTS-18 to try to clear the buffer as fast as possible. Do I really need to move to a device that supports 64 MHz? Is anybody having this thing work reliably at 32 MHz or less?
