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

b5f1bcc4d6 Split InitI2c() as InitI2cMainBus() and initI2cEepromBus() and invoke InitI2cMainBus() from PIT_I2C_WATCHDOG_HANDLER() 2017-10-03 20:43:26 +02:00
László Monda
7061345ec2 Fix hard faults by moving slaveConfig and slaveHandle out of InitI2c(), thereby making them always available for KSDK. Fixed by @santiagogf89. 2017-10-03 19:15:33 +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
László Monda
724d72132a Rearrange slave_command_t enum values a bit to reflect their relative importance and rearrange a related case block too. 2017-10-01 22:21:00 +02:00
László Monda
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
6edf4113a4 Make the slave check message integrity and only process if it's valid. 2017-10-01 22:05:20 +02:00
László Monda
1b1111e9da Rename I2C_BUFFER_MAX_LENGTH to I2C_MESSAGE_MAX_TOTAL_LENGTH. 2017-10-01 21:55:37 +02:00
László Monda
b443b56357 Rename I2C_MESSAGE_MAX_LENGTH to I2C_MESSAGE_MAX_PAYLOAD_LENGTH. 2017-10-01 21:52:41 +02:00
László Monda
4ade25d739 Add I2C_MESSAGE_HEADER_LENGTH and use it in i2cSlaveCallback() instead of magic numbers. 2017-10-01 21:42:55 +02:00
László Monda
0ba979a658 Refactor i2cSlaveCallback(). 2017-10-01 21:38:02 +02:00

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

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
894103a944 Disable the watchdog of the left half because for some reason it makes I2C recovery less reliable. 2017-09-30 20:54:27 +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

cec8bbfe01 Clone InitI2c() as InitI2cV2() and use it in the LPTMR interrupt handler to avoid the hard fault. 2017-09-30 17:06:17 +02:00

László Monda
