Part Number: MSP430FR2111 Other Parts Discussed in Thread: DRV8837EVM , Tool/software: Code Composer Studio Hello,
I am working with a motor driver evaluation module (DRV8837EVM) where I am replacing the existing MCU (G2131) with an FR2111.
The idea is…
Hi user,
To select the sense resistor, you need to determine a voltage across the sense resistor that, when amplified by a current shunt amplifier, the amplifier's output is acceptable voltage for the receiving ADC of an MCU (e.g. sense resistor sees…
Hi Den.,
At 10kHz PWM and <5V, there are many options available.
One option is the DRV8837.
If you need to automatically control the current, the DRV8834 is a possible option.
If you need higher PWM frequency, please let us know how high. Depending…
Tzion,
Thanks for the correction. I edited my typos in my previous post above and made a note.
If you are using the TI EVMs for these devices, did you remove the STATUS LED from the DRV8837EVM? This will blink and sink current, which may account for…
Other Parts Discussed in Thread: DRV8876 , DRV8837 , DRV8837C , DRV8874 We drive all kinds of motors including Brushed, Brushless, and Stepper varieties.
What about Servo Motors?
Yes we are can include those as well. A servo like the one below has three input…
Hello Kinjan,
I only reviewed the DRV8837 portion of the schematic and it looks fine. The pulldown resistor on nSLEEP is fine, but it is not necessary since nSLEEP has an internal pulldown on that pin already. The 1000uF bulk capacitor is excessive.…
Ben,
thanks for reply.
1. I didn't change the broker, still "m2m.eclipse.org" . I just did a slight modification on the ref design code. for example: changed the time zone,disable some functions through the macro definition as below
#define…
