ch32v307 ch32v307 dev board, part 3 Next step on getting an NTP server running on the ch32v307 dev board is verifying the local clock. This is part of a series on the ch32v307 dev board There's two local clocks
ch32v307 ch32v307 dev board The CH32V307 microcontroller caught my interest because it has both IEEE 1588 timer hardware and the capability to connect via gigabit ethernet. If I ported my NTP server software to it, this would
teensy Teensy 4.1 ethernet I'm a fan of the Teensy [https://www.pjrc.com/teensy/] line of microcontrollers. I have a whole pile of them for various projects. When I saw that 4.1 was combining a
ntp Embedded NTP Server Now that I got the results I wanted from my embedded NTP client [https://blog.dan.drown.org/embedded-ntp-client-ntp-interleaved-mode-part-5/], I wanted to convert it to an NTP server. I also wanted it to
ntp Embedded NTP client/NTP interleaved mode, part 5 I'll test what happens when I plug my embedded NTP client directly into my NTP servers, bypassing the Ethernet switch. This ends my long running embedded NTP client series. The systems involved Embedded

stm32 Debian for STM32MP1 I bought a STM32MP1 dev board [https://www.st.com/en/evaluation-tools/stm32mp157a-dk1.html] because it has a gigabit NIC with 1588 PTP timestamps as well as hardware timers that can timestamp PPS

ntp APU2 NTP server I bought an apu2c0. I believe it will make a better NTP server than my other NTP servers.
