From 0cf54ce07335f60642a14df7e6107422a5aeb9a0 Mon Sep 17 00:00:00 2001 From: Martin Braun Date: Thu, 14 Nov 2019 13:12:20 -0800 Subject: mpm/mpmd: Expose APIs to drive GPIO sources The N310 has a feature that allows the front panel GPIOs to be driven by various sources: The PS, or any of the radio channels. The MPM-based APIs did not expose any way to change that. Changes: - Add MPM APIs to PeripheralManagerBase and n3xx classes - Improve comments and explanations - Add host-side hooks into these new APIs in mpmd_mb_controller - Implement these APIs for N3xx The N3xx devices will have the option to set the GPIO source to "PS", or to one of "RF0", "RF1", "RF2", "RF3" (if there are four channels; the N300 and N320 can only go up to RF1). Note: The N310 radio does not have separate FP-GPIO banks for channels 0 and 1, which needs to be fixed in a separate commit. --- mpm/python/usrp_mpm/bist.py | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'mpm/python/usrp_mpm/bist.py') diff --git a/mpm/python/usrp_mpm/bist.py b/mpm/python/usrp_mpm/bist.py index e26d6d36c..b20020e1f 100644 --- a/mpm/python/usrp_mpm/bist.py +++ b/mpm/python/usrp_mpm/bist.py @@ -246,7 +246,9 @@ def get_tpm_caps_info(): return result def gpio_set_all(gpio_bank, value, gpio_size, ddr_mask): - """Helper function for set gpio. + """ + Helper function to set GPIOs + What this function do is take decimal value and convert to a binary string then try to set those individual bits to the gpio_bank.
