From cebd1fcec0f7a484ca7e8ecce76c6d9c211368ec Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Fri, 16 Jun 2006 16:14:28 +0200 Subject: Fix TRAB channel switching delay for trab_fkt.bin standalone applikation Patch by Martin Krause, 08 Nov 2005 In tsc2000_read_channel() the delay after setting the multiplexer to a temperature channel is increased from 1,5 ms to 10 ms. This is to allow the multiplexer inputs to stabilize after huge steps of the input signal level. --- board/trab/tsc2000.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'board/trab/tsc2000.c') diff --git a/board/trab/tsc2000.c b/board/trab/tsc2000.c index ca68682..382a85b 100644 --- a/board/trab/tsc2000.c +++ b/board/trab/tsc2000.c @@ -223,7 +223,7 @@ u16 tsc2000_read_channel (unsigned int channel) u16 res; tsc2000_set_mux(channel); - udelay(3 * TSC2000_DELAY_BASE); + udelay(20 * TSC2000_DELAY_BASE); tsc2000_write(TSC2000_REG_ADC, 0x2036); adc_wait_conversion_done (); -- cgit v1.1
