Code snippets for BM1387 miner
OBSOLETE, all routines (updated and bug checked) can be found in my basic-BM1387-miner

(I'm using as little as possible libraries, and try to avoid any dynamic memory allocations, so no String type variables, classes etc. This to prevent memory leaks and code bulging. This does mean that most code is for single threaded use only!)

All code is for reference only and still under construction/untested
headerprep.h - Seems to work
Function: Builds binary (as in non-ascii bytes) bitcoin blockchain header from pool data
poolio.h - functional but still limited & blocking on connect
Function: Handles I/O to pool, saves relevant data in strings.
bm1387freq.ino - fully tested but still contains tons of debug printfs
Function: Sets BM1387 frequency to any possible value between 50-799MHz in user defined resolution

My mining software state:

Right after startup:

During warmup the asics get fed random data, this activates all cores in the asics. The Antminer S9 does something similar during warmup. If I don't use a warmup my hashrate is significantly lower..
The asics run at 120MHz(asic#0) and 125MHz(asic#1), and will in time each reach the target hashrate.
The 1st hex block shows the tickets (nonces) returned by the asics, the second block the final (not yet reversed) hash. During mining stage it ends with at least 8 zeroes, success!!

A somewhat longer piece of logging to show pool I/O
