I'm still learning the C notation, so I'm still sorting out some of the the basic notation. sokrasins on "Issue accessing TIMER1 register CR2" http://forums.leaflabs.com/topic.php?id=1132#post-6968 Tue, 25 Oct 2011 10:02:41 +0000 sokrasins 6968@http://forums.leaflabs.com/ Ahh, you know what, I just figured it out. After looking through the source again, I figured the correct way to access CR2 on TIMER1 is `TIMER1->regs.adv->CR2 |= 1<<8;' because of the different register components of the different classes of timers. mbolivar on "Issue accessing TIMER1 register CR2" http://forums.leaflabs.com/topic.php?id=1132#post-6967 Tue, 25 Oct 2011 10:02:02 +0000 mbolivar 6967@http://forums.leaflabs.com/ See the timer documentation: <a href="http://leaflabs.com/docs/libmaple/api/timer.html#types" rel="nofollow">http://leaflabs.com/docs/libmaple/api/timer.html#types</a> What you want is <code>(TIMER1->regs).adv->CR2 |= 1 << 8;</code> Or, since you already know you're using timer 1, <code>TIMER1_BASE->CR2 |= 1 << 8;</code> sokrasins on "Issue accessing TIMER1 register CR2" http://forums.leaflabs.com/topic.php?id=1132#post-6966 Mon, 24 Oct 2011 22:14:55 +0000 sokrasins 6966@http://forums.leaflabs.com/ Hi all, I'm having some trouble accessing the CR2 register of TIMER1. At the line <code>TIMER1->regs->CR2 |= 1<<8;</code> the compiler throws an error "error: base operand of '->' has non-pointer type 'timer_reg_map'". This is very confusing to me, as a similar bit of code for the ADC, <code>ADC1->regs->SR ^= 1<<1;</code> will compile perfectly, and the variable all seem to be of similar types. I've poked around in the timer.h source and on the forum, though I haven't been able to find the source of my problem yet. I would appreciate some help! I'm new to developing in C and using the unix toolchain, so I apologize if it's a trivial issue. Thanks in advance!
