c707f0e408 Transfer a synchronization message to make I2C recovery more robust. 2017-10-04 02:24:34 +02:00
László Monda
efb0f982d2 Only try to recover I2C if SDA is low. 2017-10-04 01:22:22 +02:00
László Monda
2027940b4c Use the correct I2C_MAIN_BUS_{SDA,SCL}{PORT,PIN} macros at the right spots. 2017-10-04 01:04:56 +02:00

e5595bc757 Extract I2C recovery code to recoverI2c() 2017-10-03 23:59:27 +02:00
László Monda
72812724ef Now do send a STOP condition at the end of the I2C recovery which might make it more robust. 2017-10-03 23:37:16 +02:00
László Monda
1daf43b751 Set SDA as GPIO upon trying to recovering I2C, not just SDL. 2017-10-03 23:23:26 +02:00
László Monda
2804d3e447 Don't cycle SDA just before initialzing I2C. Merely pull it high to generate a STOP condition. 2017-10-03 22:05:42 +02:00
László Monda
ff1d5dffaa Cycle through the I2C clock by using 20 cycles instead of 16. Should be a bit more reliable, although I can't see a definite improvement. 2017-10-03 21:56:08 +02:00
László Monda
5de396bb68 Don't mess around with SDA and SCL before cycling through the clock because it seems redundant. 2017-10-03 21:37:35 +02:00

7af8042c93 Fine tune delay to match the I2C peripheral driven at 100kHz. 2017-10-03 21:06:04 +02:00

f1a8d9a330 Toggle SCL from a loop. 2017-10-03 20:49:54 +02:00

b5f1bcc4d6 Split InitI2c() as InitI2cMainBus() and initI2cEepromBus() and invoke InitI2cMainBus() from PIT_I2C_WATCHDOG_HANDLER() 2017-10-03 20:43:26 +02:00

90bad68287 No need to explicitly initialize slaves before starting up the scheduler as the scheduler takes care of them. 2017-10-02 00:03:51 +02:00
László Monda
f921753b63 Call slaveSchedulerCallback() instead of the update callback of the first slave to trigger the slave protocol scheduler. Given that the callback is involved from the start this should result in a more reliable startup state. 2017-10-01 23:54:46 +02:00

858586ef2a Fix data size by using I2C_MESSAGE_MAX_TOTAL_LENGTH instead of I2C_MESSAGE_MAX_PAYLOAD_LENGTH. 2017-10-01 22:12:00 +02:00
László Monda
ecc2d2db9a Use I2C_MESSAGE_HEADER_LENGTH instead of magic number. 2017-10-01 22:08:38 +02:00
László Monda

42e17ca1bf Rename masterCallback to slaveSchedulerCallback. 2017-10-01 03:15:25 +02:00

37cf632f2a Reindent Slaves[] because its lines have gotten overly long. 2017-10-01 02:53:42 +02:00
László Monda
3079d527b1 Add uhk_slave_t.disconnect() callback so that upon disconnecting the left keyboard half, the left LED driver IC can be marked as disconnected too, so it'll be reinitialized upon reconnect. This usually didn't happen because LED states are cached so the LED drivers are rarely spoken to. 2017-10-01 02:47:29 +02:00
László Monda
320923b41c Properly update uhk_slave_t.isConnected by introducing isFirstIteration. 2017-10-01 01:39:12 +02:00
László Monda
b49cb30070 Try to resurrect I2C not only in the watchdog but upon initialization. This may be useful when only the right half reboots after a firmware upgrade. 2017-09-30 22:17:44 +02:00
László Monda
b87042a44a Resurrect the state machine of frozen IS31FL3731 ICs by toggling SCL and SDA. 2017-09-30 20:34:35 +02:00
