unfortunately, channel A use serial interface with ASCII 7bits, i guess i cant use mesa_uart without modify uart.c. Does pktuart allow me to change frames? I was looking at hm2_pktuart_setup function, there is an option "Bit 20..16 Frames received", is this what i need? 2018-03-10 17:40

Re: [Emc-developers] writing new firmware to read yaskawa absolute encoder

i'm stucked at uarts because i dont really understand how UART work , i see there are many files like mesa_uart.c, mesa_uart.comp, uart.c, pktuart.c, I guess uart.c and pktuart.c contains uart's functions and mesa_uart.comp or mesa_pktgyro_test.comp will use these functions so i just need creat a

Re: [Emc-developers] writing new firmware to read yaskawa absolute encoder

sorry, my abs_encoder is 15 bit type, showing at page 56 (63 is pdf page), it hasn't phase S. The problem is phase A has 2 functions, send serial data and incremental pulses so i think i will connect it to 1 UART port and 1 encoder counter port, after receive serial data, i will reset counter.

[Emc-developers] writing new firmware to read yaskawa absolute encoder

Hi EMC developers, can i ask for a way to write a new firmware to get yaskawa absolute encoder. My knowedge is limit so i cant find the way by myself therefore i need a little bit help. The yaskawa abs_encoder is a serial abs_encoder but it's using quadrature. >From the the yaskawa document
